Veritas Cluster Server
Originally written by
- Comes from Veritas software (which is now owned by Symantec), and supports
several operating systems (including Solaris and Linux).
- An active-passive cluster. Has a very nice GUI configuration tool
(but cannot handle spaces in various resource names).
- Very common in the field on Solaris systems, until Solaris 10 - when Sun
tried to "boot it off" in favor of their own cluster software (i think
they failed - but they got some awareness and market-share).
- Often used with Veritas volume manager - which is an LVM software, and can
properly identify disk statuses.
- Normally uses SCSI reservation for I/O fencing, but can be used also
- Works only with SCSI disk devices.
